7.2.4
A data transfer control register (DTCR) is an 8-bit readable/writable register that controls the
operation of one DMAC channel.
Bit
Initial value
Read/Write
The DTCRs are initialized to H'00 by a reset and in standby mode.
Bit 7⎯Data Transfer Enable (DTE): Enables or disables data transfer on a channel. When the
DTE bit is set to 1, the channel waits for a transfer to be requested, and executes the transfer when
activated as specified by bits DTS2 to DTS0. When DTE is 0, the channel is disabled and does not
accept transfer requests. DTE is set to 1 by reading the register when DTE is 0, then writing 1.

If DTIE is set to 1, a CPU interrupt is requested when DTE is cleared to 0.
